OILING-CAN.

SPECIFICATION forming part of Letters Patent No. 267,471, dated November 14, 1882. l

Application sied April 11,1882. (No model.)

To all whom it may concern:

Be it known that I, PATRICK WALL, of Allegheny city, in the county of Allegheny and State ot Pennsylvania, have invented anew and useful Improvement in Oiling-Gans; and I do hereby declare the following to be a full7 clear, and eXact description thereof.

Heretofore oiling-cans having spring-bottoms have usually been made of tin, zinc, brass, and malleable iron. The better class of these cans have been provided with hardenedbrass bottoms, which are put in with soft solder. In someinstanees tempered-steel bottoms have been suggested, the same being secured by a wired edge on the bottom of the can-body, and in the ordinary way of securing the bottoms of oil-cans. The objection to these cans has been that the joint was bad and the cans frequently leaked. This danger of leakage is increased in cold weather, when such cans are frequently and carelessly put on the tire or stove to melt the oil. The heatto which the can was thus exposed had a tendency1 to melt the solder and cause the can to leak. Another objection has been that a brass bottom produces verdvigris, which often clogged the tube and necessitated frequent unscrewing and cleaning of the same. Another objection to this can was its great expense.

To enable others skilled in the art to make and use my invention, I will' now describe the same by reference to the accompanying drawings, in which- Figure l is a plan view of the sheet which composes the body of my improved oil-can. Fig. 2 is a view ot' the same after being formed into the body. Fig. 3 is a plan view of the bottom. Fig. 4 is a cross-section of the bottom. Fig. 5 is a view of the collar. Fig. 6 is a vertical section of the can with the collar and bottom in place, the bottom not being bra-Zed in. Fig. 7 is a view illustrating the method of brazing in the bottom. Fig. 8 isa view of the blank from which the tube is formed. Fig. 9 is a side View of the tube. Fig. l() is a side view of the finished can.

Like letters of reference indicate like parts in each.

The body a is formed of a sheet of wroughtiron of suitable gage, of the form shown in Fig. l. One edge ot' the sheet a is niched, as

at d2 a3, and the lips so formed are bent at an angle in opposite directions. Then the sheet a is bent around, and the straight edge c4 is inserted between the lips a2 d3, which are hammered down upon it, so as to secure the sheet in the shape ot' the body a and ready for brazing. Then the spelter or brazing material is placed upon the seam a5 thus formed, and the body ct held over the tire bin such avposition that the flame will strike the outside of the body along the line of the seam. This causes the spelter to melt downand the seam to be seeurelyand tightlybrazed. The bodyathus formed is shown in Fig. 2. It is then taken and put through a Hanging-machine of ordinary construction, and the recess or groove c is formed in the lower end, as shown in Fig. 2. I then take a collar, c, formed ot' either malleable or wrought iron, and place it in the small end of the body c, securing it there by drawing a tool around it, and place spelter or brazing material c' in the inside of the body around the edge of the collar c, and then eX- pose the upper end of the body to the fire b. The flames striking the outer surface will melt the brazing material and cause it to lrun inbetweeu the collar c andthe body a, and thereby fasten the collar c in place and forni a tight joint between the collar and the body. I then take a bottom, d, formed of sheet-steel by stamping in suitable dies, with a flange, d', around its edge, and place it in the bottom ot' the body (t, so that the iiange d shall iit into the groove c6. l then bend the lower edge of the body c around the lian ge d', either by hammering or by means of a crimping-machine, so as to secure the bottom d tirmly in place, as shown in Fig. 6.

In order to make a tight joint, such as will prevent the leakage ot' oil between the body a andthe bottom d, I braze the joint in the following manner: I place the spelter or brazing material around the edge of the bottom, as shown at c in Fig. 7. I thenexpose the can to the lame of the tire bin such a manner that the name shall strike the outside of the body a and shall'not come in contact with the steel bottom d. The heat passes through the edge of the body a, melts the spelter, and causes it to flow into the joint between the body c and the bottom d, completely tillingit IOC and making a close, tight joint. The can c is turned around and the spelter applied until the entire circumference ofthe bottoin has been brazed in. 1t is necessary in this operation that the tlaine ofthe re b should not come in contact with the steel bottoni d, because the effect of such contact would be to burn the steel and destroy its resilience. rlhis ofcourse would destroy its utility as a springbottoin. 'lhe lower edge, e', of the can a is then ground oli" for the purpose of finishing it and giving it an even bottoni, there being some irregularity produced by the operation ot' turning in the lower end ot the body a over the 'flange d.

The tubef is formed of a sheet, ff, Fig. 8, which is bent into a tubular forni and brazed along the seam f2, Fig. 9. It is then threaded externally at thi` lower end and screwed into collar c, thereby completing the can. The result ot' this construction is thatl obtain an oiling-can which is cheap in construction and material, capable ot' a fine finish, and which has a very much 'better spring-bottom thanv any used heretofore, whichcan be placed upon the stove ['or melting the oil without danger,

which is provided with tightjoints, and which will not clog up in the tube.

lf desired, the collar 0 may be niade ofbrass or other material. Il', however, it is to be secured in place by brazing, the material used must be such as will stand the heat. A brass having a large percentage of copper will answer for this purpose. Y

The method herein described of inserting the bottoni by turning the edge a in around the flange d of the bottoni d and then brazing it to make a tight joint may be practiced in the manufacture of mill-lamps and similar articles.

What I claim as iny invention, and desire to secure by Letters Patent, is-

An oilingcan orsiinilar vessel havingashcetmetal body and a steel spring-bottoni, the parts being united by a lapped and brazedjoint, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand this 3d day of April, A. l). 1882.
